When you play a negative progression,the best thing you can do is ,start with the smallest bet. Start on the quads is better than the splits.Suppose the next sequence 22 35 3 9 15 18 then my next bet shall be 2 units on 1/6, 7/12, 6+3 units on Hign and 1 unit on quads 19/23, 25/29 and 31/35. The 3 extra units on High are the insurence for the quads.

Right, in principle the quads SHOULD be less expensive but they aren't. The reason is because they are 2 full betting places below the splits; so what they gain in chip cost they lose in payout -- EXACTLY 1:1. So, since the payout for the splits are better, it only makes sense to do splits.

The figures looks terrible high, but can in money be acceptable on a penny wheel. 10000 cent is less than a days income here.

If we look at it as fractions, just move the decimal point a few step and it do not looks so terrible.An Martingaler betting 8 steps start with 1 Euro are betting 100, 200,400,800,1600,3200,6400,12800.

Looks high is high but no bets is far over 100 Euro.

As long the player have fun, and do not get in problem, he can win some cents or lose some Euro, he could as well spent it on entertainment of other kind.

It is a step progression for my taste, but there are too slow as well, like up one on a lose and one down. The bets are seldom high, but the bank can be back VERY MUCH with no hope of ever catch up.

The too carefully player lose or break even, it is a game and there is risks. If possible I only play on NOZ and small value chips, which make my bank looks large.
